pari-dev,
     I recommend that algdep(x,k,0) never be used, or else the
default for algdep(x,k) should be changed. The reason is because :

? algdep(1+.1^6,1)
%1 = 1080516752824585954039985431*x - 1080517833341338778625939471

happens far too often. I fail to see to reason why this is the default
when it seems that algdep(x,k,default(realprecision,,1)) returns much
more reasonable results more often. Shalom, Michael
